    Already found the diode - but thanks.

        Thanks - I just updated my post #19 to add the diameter. It's in inches though - I don't have any tool that measures in metric.

          Just to get the sizes right: dia. X height, LS means lead spacing. These are always in Metric though.
          Originals look like CapXon KM series rated 2,000hrs life. So I took those dimensions as a start:

          C3, C10 - 100uF 16V 6.3x11mm LS=2.5mm
          C4 - 470uF 25V 8x11.5 or 10x12.5, LS=3.5mm
          C5 - 1,000uF 25V 10x20mm LS=5mm; but looks bigger, is this a 12.5mm part (1/2")???
          C13, C14 - 0.47uF 50V electrolytic 5x11mm LS=2.5mm?
          D11 - 1N5231B 5.1V 0.5W zener
          U4 - L78L08ACZ voltage regulator 8V 0.1A
          Relays - Siemens T7CV5D-12-02, 10A 250VAC, 12VDC coil.

          If this is right, we can give some possible part numbers for the caps.

            C3, C10 - 100uF 16V 6.3x11mm LS=2.5mm (YES, Correct)

            C4 - 470uF 25V 8x11.5 or 10x12.5, LS=3.5mm (I get 9mm X 16mm tall)

            C5 - 1,000uF 25V 10x20mm LS=5mm; but looks bigger, is this a 12.5mm part (1/2")??? (I get 13mm X 21mm tall)

            C13, C14 - 0.47uF 50V electrolytic 5x11mm LS=2.5mm? (YES - CORRECT)

            The black skinned caps are marked "KM" and the orange skinned pair (C13 and C14) are marked "LL" - I'm not absolutely accurate on the sizes. I'm using a measuring tape, then converting decimal to metric. So, I'm close, but could be off slightly.

              Caps come in standard (Metric) size categories. Look for these long life parts:

              C3, C10 - 100uF 16V 6.3x11mm LS=2.5mm bent to 3.5mm (OK to sub 25V parts)
              Nichicon ULD1C101MED1TD
              Chemi-con ELE-160ELL101MF11D or ELE-250ELL101MF11D (25V).
              Rubycon 25YXM100MEFR6.3X11
              ---------------------------------------------------------------------------------
              C4 - 470uF 25V 10x12.5mm LS=5mm (long life parts are usually taller like 16 or 20mm)
              Rubycon 25ZLH470MEFC10X12.5
              Nichicon UHE1E471MPD6TD or UHE1E471MPD6.
              Chemi-con EKY-250ELL471MJ16S
              Panasonic EEU-FR1E471
              ---------------------------------------------------------------------------------
              C5 - 1,000uF 25V 12.5x23mm LS=5mm; more common size is 10x20mm
              Chemi-con EKY-250ETD102MK20S 12.5x20
              Nichicon UHW1E102MPD 10x20
              Panasonic EEU-FR1E102 10x20
              Rubycon 25ZLH1000MEFC10X23 10x23
              ---------------------------------------------------------------------------------
              C13, C14 - 0.47uF 50V electrolytic 5x11mm, instead use 0.47uF 50V polyester (these have no polarity) w/leads splayed out a bit, like Kemet

                Does the polyester cap still need to be Low Leakage like the original caps? I can't find one that has that spec (at all). Thanks for looking up the others.

                  A film capacitor inherently has much less leakage current than any electrolytic capacitor, so I see no penalty to using them aside from the lead spacing being a bit bigger at 5mm.

                    some polyester are tall and square if you look hard enough - those can fit inplace without any lead bending
                    dont skip looking at 63v and 100v ones to find a good size/shape

                      Frigidaire oven control board repair 316131600

                      The board has 5mm hole spacing, with the original 0.47uF having their leads bent out to that. So 5mm I think is fine. I did see some 2.5mm polyester caps but no stock anywhere. Wild guess they are for filtering the temperature sensors.

                        I found some Nichicon .47uf, 50V, low leakage electrolytic caps on DigiKey. The only difference was they are rated 1,000 hour (vs 2,000 hour).

                        Would these be a better choice than a poly film cap?

                            I found only one polyester cap (with the correct specs) on Mouser - aside from the mounting style, do you think it's a good replacement for the original electrolytic 0.47uf, 50V, 105c Cap that is no longer available?

                              50v is uncommon for film caps - you should have used 63v in your search.
                              a better fit for less than a third of the price

                                Yes, best at Mouser is Kemet R82 series: 0.47uF 63V polyester $0.37 LS=5mm

                                  Thank you - that is a much better fit physically.

                                    Thank you (for all your help). I just put the KEMET cap in my cart and will order it.
